Thisinvention relates to improvements in articles of the above f mentioned classV in Vwhich the well known educational scroll is embodied; such articlesbeing intended for f l and used chieflyV in juvenile entertainment,`

' instruction, andl educational work in the studio, school room, and'home'. Obj ects of the invention' are to provide an article of the kind` described, whichis veconomical of manufacture, compact,- durable and serviceable ;'and which comprises in a single unit, a blackboard Vand stand, and a case for thefsupport of the scroll and the retention'of working materials; there being embodied vin Lkthe case construction,l a body plate which constitutes a back or cover plate therefor, and whichv also'constitutes a Working' surface or table top'when the case and jj. blackboard are'i the folded Hor'collapsed j .Further aims of they invention are to pro;- vide features `off-constructiony whereby the blackboardand case are'easily available for use either in combination with each other,"or

lnther` blackboard stand c and work case shownI herein as the preferred formof emc5 i bodiment of my invention, the support frame 1s of widthiand depth toac'comodate a blackboardv about .fourteen bysixteen linches in" dimension, Yand `comprises the four wooden uprights' 1,: 2,' 3,. and 4. The bottoms of the Z0 uprightsl and are secured to affooted cross 'bar'5; and thebottoms VVof the uprights 2 and l-jaresecuredto a footed cross .bar v6. yThese f`ooted' `cross bars are similar ytoeach other and their endportions'etend to the front and 75 to therearof the said uprights, the relative distances as shown in Figure QQ The height from thebottom of the footedcross bars to thetop ofthe frame, is about ei ghteen' inches.

Upon the upper ends O fthe'said uprightsare- 'sn secured the frame `pieces7,`8,9 and 1Q.V

A case structurel which isadaptedto repose on'the said support frame, and is kcolmected to one sidethereof by hinges 1 1, consists `of body memberslQ, 13,14: andl'," secured to;- 85

` gether` at their corners.l A Upo'n the inner Aface 'and nearthe frontaledge ofeach ofthe lmembers '14C fand 1,5,"i's' a groove' 1 7 of the length, as shown infFigure lfjA' light wooden reg'.

tangular frame `18whose ends rest movably e0 in thesaid'groovesl, constitutes a trim or mask .in front of the space occupied bythe scroll 19, The saidA scroll kcomprises aflexible "textilesheet bearing lthe usualjmis'cellaneousv sets of lettering-,ff diagrams, images, numerals, and educational.illustrationsxincidenttoscrolls ofits class, and' includes the complemental rollers 2O and y21.` One end of each'Sofmthese-'rollers,is plain, and itsother end is 'provided with a central longitudinal 100 bore 23. Spaced recesses 22 in the case member constitute bearings for the plain ends of the rollers. Spaced holes 24 are provided in the case member 14 in positions aligned with the said recesses 22. To install the scroll, the rollers are disposed with their'plain ends in the recesses 22, and the knobbed pintles 24a, disposed in the holes 24, are inserted into the bores 23 of the rollers, and there secured by a nail or screw'25. By the rotative movement of one or the other of the rollers, the

vscroll sheet may be moved so as to present to view the different sets of characters thereon.

To yieldably hold the rollers against movement, and also to yieldably hold the mask frame 18 at the position shown, I provide a holder device of the form and construction shown in Figure 7. This holder device consists of a spring wire of predetermined length whose bowv shaped body portion 26 is rsecured to the case member 14 by a staple 27. rlhe oneend portion of the wire presses lirm y ly against one of the pintles24a, andthe opposite portion of the wire'isof form to bear against the other ofthe pintles 24a, and is brought about in such formation that its curved inturnedend 28 bears firmly against the rear face of the end of the mask frame 18. Thel reason for holding the mask frame yieldably in its position will be presently referred to. Y

In the lower portion of the case, is disposed longitudinally a light thin plate 30 which is set at an incline, as shown in Figure 5., and

Y at such height that a narrow space ,81' ybetween said plate andthe adjacent case member, is provided. The compartment thus formed is adapted to retain crayons, chalks, papers, and suchothe'r working materials as may be desired." Accumulation of dustfparticles orsediment is avoided by having the openspacel.V i i Carried Vby,'and`secured to the case members 12, 13, 14 and 15, is a body board or plate 32 which is1 ofthe suitable Vdimensions las shown in the drawings.

A blackboard 33 which is provided with suitably moulded sides 84, has each corner V`of itsV frontal Vportion pivotally connected by pivotpins 35 to the side'members 8 and 9 of the support frame. To register Ona plane slightly below the planeof the'blackboard is a trough piece 36, .which is adaptedtoreceive and'retain conveniently,the crayons or lother working implements which may roll coengagement with the sides of the blackboard. By this construction, combination, and'arrangement of parts, the case when in registration with the support frame, as shown in Figure 8, retains the blackboard in position immediately underneath same. The compartment plate 30 being` inclined, as shown, prevents all tendency of the contents of the compartment, to become displaced when the case is swung to the lowered positionxri ,g

By' my invention, a minimum amount of material is required, and there is substantial economy in the work and labor involved in the processing of the several parts, and in the assembling of said parts into the finished product. Advantages of having the mask frame retained movably in its position, are that access to the space occupied by the scroll is easily available. i Y

' Aliso there is afforded facility whereby economy may be `practiced in the finishing of thev interior of the case, either by spraying, vor by applying paint or enamel with a brush.

yThis 1s an item of considerable importance in the manufacture of articles of this class, as hitherto, the finishing of the severa-l interior surfaces; and the installing of the renewals or replacements incident to the use of the scroll,r have been relatively inconvenient and costly.

i VMy improved .blackboard stand and work case maybe supplied to the trade in the completely assembled.y status, as shown; the case being in repose upon, and the blackboard being retained in horizontal position within the upper portion of the support frame. To use the invention, thev case is swung to the upright position; the blackboard being coin-` cidentally brought up to the inclined position as shown in Figure 2 and Figure. The connector .bars 38 .constitute supports for the blackboard, and they alsol constitute stays whereby bothv the blackboard and the, case are automatically maintained in their respective positions. The tendency of the case to bear rearwardly contributes to the stable support and retention of the blackboard at. its raised position, and inwhich said'position itis available to the user for writing or drawing on its surface with crayon or chalk, or forV theuse vthereof as adesk. Thecomp artmentfprovided by the plate 30 is conveniently available forv the retention of chalks, crayons, papers and working material.; and the scroll is in convenient position for observation, and the knobbed pintles for operating the scroll, are within easy reach. Theweight of the-body board 32. imparts such .tendency of thecase to bear rearwardly, that it is automatically retained stably' in the upright position ,Fat'fthe Sametime it iscapable Vof being easily changed to the horizontal position of repose on the support frame. With the several partsof the invention in the status as shown in Figure 8, the article is Y useful as a table; the scroll and blackboard, andthe contents of the compartment, and also such papers as may be lying on the blackboard, being suitably retained and shielded from misplacement or injury. The body board 32 constitutes a convenient and useful working surface or table top.

Whereas I have shown my invention in the form and proportions, and the details thereof, in the construction deemed preferable, it will be understood that minor changes may be made in the several parts and features of construction, within the scope of the invention as defined by the appended claims, Without departing` from the spirit of my invention, or sacrificing any of its advantages.
